https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D216759 --- Comment #1 from andrew@azar-a.net --- Memory disks show writes are perfectly fine. KVM: # mdconfig -a -t swap -s 128m -u 1 # dd if=3D/dev/urandom of=3D/root/test bs=3D1M count=3D128 # dd if=3D/root/test of=3D/dev/md1 bs=3D1M 128+0 records in 128+0 records out 134217728 bytes transferred in 0.089190 secs (1504858419 bytes/sec) # dd if=3D/root/test of=3D/dev/md1 bs=3D1M 128+0 records in 128+0 records out 134217728 bytes transferred in 0.056503 secs (2375411572 bytes/sec) So seems some specific sysbench call ruins everything. Should we add [benchmarks/sysbench] ? --=20 You are receiving this mail because: You are the assignee for the bug.=
